The crashes look quite random -- I don't think this is a bug in the core of Xen. The two most likely possibilities are that you have duff memory or that a misconfigured device is trashing memory. I definitely wouldn't discount the former, even though native x86 Linux has been running okay -- crashes can be very sensitive to memory layout. It might be worth running a few rounds of memtest on the machine, or swapping the memory, or trying to boot Xen on another identical box. If that doesn't cure it then try swapping out or disabling hardware. For example, boot off local disc and disable networking ('ifname=dummy'). Since the cause is most likely hardware-related, the best approach is to isolate the problem hardware. -- Keir PS. If you build your own Xen/Xenolinux then keep the build trees around (or at least, for Xenolinux, the 'vmlinux' file). I can't find suitable image files for the tarballs on the Xen website, and without them it is very difficult to determine anything from crash dumps. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
